Also known as: Pyloromyotomy, Surgery for pyloric stenosis

Pyloric stenosis is always treated with surgery (pyloromyotomy). After your baby has the surgery, pyloric stenosis usually will not develop again.

Types of surgery

Two methods of surgery are used to correct pyloric stenosis—open surgery and laparoscopic surgery. Your doctor will choose which one is best for your baby.

  • During open surgery, a small incision is made in the baby's abdominal wall. The ring of muscle (pyloric sphincter) is then cut to widen the channel between the stomach and the intestine.
  • During laparoscopic surgery, an instrument called a laparoscope is inserted through a small incision made in the baby's belly button. The laparoscope provides access to the pyloric muscle so the muscle can be cut. Several other small incisions are usually needed.
